Please answer a-e because I need to study for an exam.

You decided to create the first synthetic eukaryote. Its genome has virtually no intron sequences. Here is a region of the genome. The locations of the open reading frames are marked with gray boxes. The arrows indicate the direction of transcription for each gene. The figure above shows a close-up of the DNA strands of the marked region. Mark the template and coding strands. is the promoter to the left or to the right of GeneX? is the polymerase moving to the left or to the right? Transcription starts at one of the two bases marked with asterisks(*). Write out the bases of the newly formed mRNA strand. Mark the 5\' and 3\' ends. Translate your newly formed mRNA strand (starting with the 5\'AUG 3) using the single-letter amino acid abbreviations from the codon table. If you have done everything correctly, you will get a confirmation message spelled out in the amino acids.

Solution

a. ANS:

The two strands of the DNA are anti parallel the replication of DNA occur in opposite direction since DNA is always synthesis in 5\'-3\' direction.

As the replication pork moved in one direction the DNA copies continuously in both strands. Then the replication missionary should be able to synthesize in both 5\'-3\' and 3\'-5\' direction.

But the DNA polymerase involved in replication can added a new nucleotide only to 3\'end of growing chain. So DNA always synthesized in 5\'-3\' direction, template strand should be in 3\'-5\' direction.

e. ANS:

m RNA is the messenger RNA that act as an intermediate between the gene and polypeptide. Translation always began from a specific codon AUG or GUG, hence it called as start codons.

The importance of the start codon is established the correct reading frame of the codon sequence as the nucleotide sequence of the m RNA can be read in three possible reading frames.

The newly synthesized m RNA strand (starting with 5\' AUG 3\') using the single letter amino acid abbreviates the amino acid \"Methionine\". So the conformation message spelt out in the amino acid methionine (AUG).
